Aircraft involved

Probable cause & findings

The pilot’s encounter with a downdraft while maneuvering low-level, which resulted in a collision with terrain.

Factual narrative

While maneuvering a float-equipped airplane low-level over a river, the pilot turned the airplane downwind and it encountered a downdraft. The airplane subsequently lost altitude and the pilot added power to climb; however, the airplane’s float impacted a gravel bar adjacent to the river. The airplane came to rest in an area of gravel-covered terrain, sustaining substantial damage to the fuselage. The pilot reported there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
